The DSP-TDR is designed for field use and has step technology, which enables it to show smaller faults, removes blind spots and maintains accuracy for detecting impedance over the entire length of the cable. Automatic impedance matching enables faster trace results without pulse width adjustments. In addition, the TDR finds faults closer to the user (no blind spot) with a resolution of less than 1 foot. The higher energy step TDR has an improved signal-to-noise ratio and digital averaging, eliminating noise interference and producing a much more detailed cable image than available with a pulse TDR.
Judge's Comment: "I love this product. The step function with no dead-zone is a plus. The ability to log the GPS coordinates automatically and automatically upload active results is fantastic. Location of test ends and documentation is important."
